1 Claim.v (Cl. 22S-5.7)

1 This invention relates to improvements in containers and has particular reference to the closure portion thereof.

It is an object of the present invention to provide an improved container in which the closure K or cover maybe readily applied and removed but which will be firmly and tightly retained against accidental displacement when it is locked in place.

A further object is the provision of an improved container which may be used and re-used many times and in which the closure may be repeatedlyv applied and removed without damage or injury to the associated parts and without adversely aiecting the ability to tightly retain the closure in position.

` Another object is the provision of a container which is re-enforced in an improved manner at proved container of the above character which is,

relatively inexpensive to manufacture, which does not require special equipment, skill or training to fill it or to apply the closure thereto and which is of ruggeed construction so that it will provide satisfactory service over a relatively long period of time.

This application is a division of my co-pending application Serial #123,414 filed February l, 1937, for Container now Patent No. 2,382,858.

For a fuller understanding of the invention, reference should be had to the accompanying drawing in which:

Fig. I is an elevational view partly in section of a container embodying my invention;

Fig. 2 is a detailed sectional view of the upper portion of a modied type of container; and

Fig. 3 is a similar view ofr another modified type of container.

Referring to the first form of my invention shown in Fig. 1 the container comprises generally a body member 6 a removable closure 1 and a base or bottom member 8. The body member may be of any desired -cross-sectional shape and may be made of any suitable material. In the illustrated embodiment the body member is cylindrical in shape and is made of laminated bre sheets wound around a mandrel. Drums or containers having fibre bodies are well-known and are in widespread use.l i

Divided and 'this application J une 19,

tionship I encircle each end of the drum with a band made of suitable material having the required strength and durability. 'For this purpose, I may use a band ,9 made of sheet metal such as steel which encircles the outer surface of the drum overlapping the end thereof and extending to the inner surface where it is bent inwardly as at I into engagement with the material of the drum body. At its opposite end the band is bent inwardly at i2 also into engagement with the materialof the drum, the ends I0 and I 2 serving to securely hold the band in position.

0n the exterior of the drum the band is formed with an annular rib or bead Ii which provides a retaining shoulder cooperating as will be later explained to retain the closure and basein position. The band 9 at the upper and lower ends of the drum may be of similar construction as illustrated in Fig. 1.

The closure l may be made of any suitable material such as metal, plastics, wood or fibre. In Fig. 1 I have illustrated a closure made of laminated` ilbre and having a central circular portion fitted into the drum and an annular U- i shaped portion I4 which fits over and straddles the wall of the drum in the manner shown.. The

' portion of the head which depends downwardly on metal as, for instance, steel. The rim is of the To re-enforce the drum, adjacent each end and general type shown in my co-pending application serial #123,414 filed on February 1, 1937, for container now patent No. 2,382,858 and consists of a unitary strip of metal formed into a band with overlappingends and having suitable locking means connecting the two ends. .The locking means preferably takes the form of vlever I6 which is pivotally connected at rI'l to one end of the band and pivotally connected as at i8 to the other end of the band. The two pivotal connections are so arranged that they are offset or misaligned in the manner shown when the lever is in locked position whereby any expanding forces exerted on the rim only serve to lock the 'Ihe rim may be expanded by raising the lever i 3 tracted by pivoting it downwardly to horizontal position as shown in Fig. l. To retain it in locked position the lever may be formed with a depending portion Il for inter-engagement with strap 20 which is formed outwardly from the material of rim I 5.

Adjacent its lower edge the rim I5 is inwardly offset as illustrated at 2| forming an annular internal shoulder which cooperates with and interengages with the annular rib Il. It will thus be seen that the head may be assembled over the end of the drum, the locking rim IB may then be assembled around the exterior of the upper end of the drum with the shoulder 2l engaging with the rib Il and the lever Il is then operated to contract the rim to lock the parts in assembled relationship.

The frictional engagement between the rim and closure are ordinarily suiilcient to retain the closure in position. However, if desired the rim may be provided with spaced lugs or spurs 22 which project inwardly, inter-engaging with the depending flange of the closure forming a positive engagement therewith.

The ilxed base l may be similar in construction to the removable closure 1. of laminated fibre as shown and is provided with a circular central portion fitted into. the drum Thusit may be made and with an annular U-shaped portion 23 which overlaps and straddles-the wall of the drum having a portion engaging the outer surface thereof.

The base may be held in position by a removable clamping rim similar to rim l5. If desired, however, a fixed rim similar to that illustrated at 24 may be employed.

The rim 24 consists of a strip of material formed into an annular band with the two ends thereof permanently secured together and to the drum and base as by means of rivet 25. The band 24 is also .provided with an annular offset providing a shoulder as illustrated at 28 which inter-engages with the rib Il whereby the band is prevented from withdrawing over the end of the spurs 21 Yformed into the band and projecting into the peripheral flange on the base.'

and rests on the wall of the container. The head maybe made of any desired material such as wood, plastics, bre or metal. When a seal of the type shown is employed I have found that ver!! satisfactory results are obtained by forming the head of wood. The seal 29 serves not only to seal the closure but also serves to re-enforce and to give additional support to the head.

In this form of my invention the head is likewise preferably retained against displacement by means of a suitable locking rim as indicated at 3l. This may be formed of a split band of the type shown in Fig. 1 with a suitable locking lever connecting the two ends. It is also provided with an annular shoulder 32 for inter-engagement with' the rib I I. The upper end of the band is preferably formed with an inwardly projecting flange 33 which overlaps the flange of the head and prevents it from becoming displaced, when the rim is locked.

In the form of my invention illustrated in Fig. 3 the body portion of the drum is not re-enforced by a band at its end. Thus, I show a body portion 34 which is formed or moulded adjacent its upper end in the manner shown so as to provide aninternal groove 35 and an external rib 3B providing an annular shoulder which may serve in a similar manner to the rib Il for retaining the closure inA Vassembled relationship. In Fig. 3 I have illustrated a closure similar to that in Fig. 2

comprising ahead 28 formed with an annular .flange 3i) and having Ia. seal 29. The locking rim 3l illustrated in Fig. 3 is also similar to that t shown in Fig. 2 and operates in a similar mandrum. A positive engagement between rim 24 f and the fixed base 8 may be provided by lugs or It will thus be seen that in the container illus- Vtrated in Fig. l I have formed a re-enforcing band around each end of the body of the drum and that the reenforcing band provides an annular projecting shoulder which inter-engages with a shoulder on a retaining rim. The retaining rim `my invention in which the body portion is similar in construction to that illustrated in Fig. l. Thus the container comprises a body 8 having a reenforcing band 9 disposed around the upper end thereof. However, in this form of my invention I have illustrated a modified type of closure and locking rim. The closure comprises a head 28 and a sealing member 29 disposed beneath the head. The sealing member may be made of paper suitably coated to resist moisture and solvents or it may be made of plastic material such a moisture-proof Cellophane or of a thin sheet of metal. At any rate, the seal preferably extends across the lower surface of the head 28 overlaps the end wall of the container and depends downwardly around the exterior thereof as shown.' The head 28 is formed so as to fit into the end of the container and it has an annular flange 30 which overlaps combined with the container shown in Fig. 3 if desired.

It will thus be seen from the above description of the several illustrated embodiments of my invention that I have provided an improved container of light anddurable construction which can be repeatedly used without appreciable wear and in which the closure may be readily applied and removed but` will neverthelessbe tightly held in position when locked. Modifications may be made-in the illustrated embodiments of my invention Without departing from the invention as set forth in the accompanying claim.

I claim: I

A container comprising a tubular body portion made of fibrous material and formed with a circumferential bead adjacent but spaced from the end thereof, said bead presenting a relatively sharp shoulder facing away from the end and a tapered surface facing towards said end, a closure having a portion fitted into ythe end of the body portion and a split clamping rim embracing the end of the tubular. body portion and having an inwardly projecting flange overlapping the'perlpheral portion of the closure, said split rim being expandable to open position to provide for its removal and being contractable to'closed position gripping the end of the body portion and pressing it into engagement with the closure and said rim having an inwardly projecting circumferential shoulder interengageable with the shoulder of said bead when the rim is in closed HERBERT L.
